Often called 'belly button surgery', laparoscopic surgery
involves small (1/4 inch) incisions in the abdomen (usually three) through which
major surgical procedures can be performed. The first of these incisions is made
in the umbilicus ("belly button"). A laparoscope (something akin to a telescope)
is placed through this incision and attached to a small videocamera. The video
image is viewed on a television monitor in the operating room. By moving the
laparoscope closer to the pelvic organs, magnification up to 6 X can be achieved.
After the laparoscope is placed through the umbilicus,
two or three other small (1/4 inch) incisions are made in the abdomen, usually
in or near the pubic hairline. Electrodes, lasers, instruments and sutures are
passed through these incisions to complete the operation. These instruments are
very small (from 1.5 to 4.5 millimeters in diameter).
The combination of small instruments and magnification
enable surgical precision that is almost impossible to achieve at laparotomy. By
comparison, there is no magnification of the operative field during laparotomy,
and the surgeon's hands and large surgical instruments obscure the operative
field. The precision attained during laparoscopic surgery becomes extremely
important when the gynecologist is treating endometriosis, adhesions, ovarian
masses, and gynecologic cancer.
By comparison, Laparotomy (the technique by which most
gynecologic procedures are accomplished) involves an incision in the abdomen
usually measuring 5 to 11 inches long. This incision is horizontal (the so-called
"bikini" incision) or vertical (from the pubic bone to the belly button). This
large incision is required for gynecologists to use standard surgical
instruments. This significantly larger incision is associated with a much longer
recovery, more postoperative pain, longer hospital stays, and more potential
complications than the same procedure performed by laparoscopic techniques.
The advantages of laparoscopic surgery over conventional
laparotomy are unquestioned. Most patients undergoing laparoscopic surgery are
dismissed the same day, although a few may require an overnight stay in the
hospital. Recovery (return to normal activity) from laparoscopic surgery is 3 to
5 weeks shorter than comparable procedures performed at laparotomy. Patients
experience less postoperative pain, shorter and more comfortable recovery,
outcomes are at least as good (if not better), and costs to the healthcare
system are less when gynecologic surgery is performed using laparoscopic
techniques.
Why are so few major gynecologic procedures performed
laparoscopically? The answer is relatively simple. Major laparoscopic surgical
procedures are difficult for most gynecologic surgeons to master. The
gynecologist must perform many simple laparoscopic procedures to develop the
skill necessary to perform the more complex surgeries. They must perform these
procedures on a regular basis to develop and maintain expertise. Unfortunately,
the average gynecologist in the United States performs only one surgical
procedure each week, a case load insufficient to develop or maintain skills
necessary to perform the more advanced (complex) laparoscopic procedures. As a
result, unfortunately, most gynecologic surgeries for benign disease are still
performed abdominally, although experts throughout the country agree that the
vast majority could safely and efficiently be performed laparoscopically.
